Chameleon Ultra DevKit

The Chameleon Ultra DevKit takes the same battle-tested nRF52840 platform as the Chameleon Ultra and opens it up for developers, researchers, and advanced users. The bare PCBA exposes all programming and debug breakout points with silkscreen labels organized in logical groups — so you can flash custom firmware, probe signals, and extend functionality without adapters or guesswork. All IO accessible. Full JTAG/SWD debug interface for breakpoints and live register inspection. If you're writing custom RFID protocols, building a novel emulation attack, or contributing to the open-source ChameleonUltra firmware — this is the hardware you need. Ships with the same capabilities as the standard Chameleon Ultra: simultaneous LF + HF RFID emulation, 8 card slots, Bluetooth 5.0, MIFARE cracking, and full read/write support across the ISO14443A ecosystem. No enclosure — this is for bench work and integration.
